OK i'll reword it... It may have killed each driver I have connected its wires onto. Question is HOW?
And...HOW can I check if its the motor the faulty one or the wiring up to it that has a short or something?
The voltage drop to 11V is not a fact, as I never checked the voltage on this printer before, probably came "underrated" from factory.
Controller is fine.
Once again, nothing seems fried to the eye, no smoke, no sparks, no cripping noise, no smell, no nothing that makes you think you fried something. The echo:busy: processing comes from Marlin each time I try to send several movements at once, but stays there "almost" indefinetly.... I do recover control on the board after a minute or so, but steppers no longer work.
So initial question is once again how do I test either / both the particular wiring or extruder motor for faults without actually frying anything else, either in this board or a new one.
EDIT: Just for reference, I replicated sending multiple QUICK command sucessions (move X move Y move X move X move Y move Y move X move Y move Y move X etc.) to a clone printer and I couldnt get marlin to drop a single "echo:busy" :????????
